Apart from driving style, consumption is
dependent on many factors such as, e.g.: Rload
R tire pressure
R cold start
R choice of route
R electrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried
out using the following three categories:
R
Acceleration(evaluation of all accelera-
tion processes):
- The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration
R
Constant(assessment of driving behavior
at all times)
- The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- The bar empties: fluctuations in speed
R
Coasting(assessment of all deceleration
processes) - The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
- The bar empties: frequent braking
An economical driving style specially requires
driving at moderate engine speeds.
To achieve a higher value in the categories
AccelerationandConstant:
R observe the gearshift recommendations.
R drive in drive program E.
On long journeys at a constant speed, e.g. on
the highway, only the bar for
Constantwill
change.
The ECO display summarizes the driving char- acteristics from the start of the journey to its completion. For this reason, the bars change
dynamically at the beginning of the journey.
On longer journeys, there are fewer changes. For more dynamic changes, carry out a man-
ual reset.
For further information on the ECO display,
see ( Ypage 196).
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shifting to
a lower gear in good time. This allows you to
take advantage of the engine's braking
effect. For this, you need to have selected
manual drive program M. This helps you to
avoid overheating the brakes and wearing
them out excessively.
When you take advantage of the engine's
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road sur-
face. This could cause damage to the drive train. This type of damage is not covered bythe Mercedes-Benz warranty.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive
program Mis temporarily activated: the auto-
matic transmission may switch to the last
active automatic drive program Eor S. The
automatic transmission may shift to a higher
gear. This can reduce the engine's braking
effect.

Heavy and light loads
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. Thisincreases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy load, do not stop the vehicle immediately.
Drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rain
without braking, there may be a delayed reac- tion from the brakes when braking for the firsttime. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm up
the brake discs, thereby drying them more
quickly and protecting them against corro-sion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt
residue may form on the brake discs and
brake pads. This can result in a significantly
longer braking distance. R
In order to prevent any salt build-up, apply
the brakes occasionally while paying atten-
tion to the traffic conditions.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
Servicing the brakes
!If the red brake warning lamp lights up in
the instrument cluster and you hear a warn- ing tone while the engine is running, the
brake fluid level may be too low. Observe
additional warning messages in the multi-
function display.
The brake fluid level may be too low due tobrake pad wear or leaking brake lines.
Have the brake system checked immedi-
ately. This work should be carried out at a
qualified specialist workshop.
!A function or performance test should
only be carried out on a 2-axle dynamom-
eter. If you are planning to have the vehicle tested on such a dynamometer, contact an
authorized Mercedes-Benz Center to
obtain further information first. Otherwise,
you could damage the drive train or the
brake system.
!As the ESP ®
system operates automati-
cally, the engine and the ignition must be
switched off (the SmartKey must be in posi-
tion 0or 1in the ignition lock) if:
R the electric parking brake is tested on a
brake dynamometer (for a maximum of
ten seconds)
R the vehicle is towed with the front axle
raised.
Braking triggered automatically by ESP ®
may seriously damage the brake system.
All checks and maintenance work on the
brake system must be carried out at a quali-
fied specialist workshop. Consult a qualified
specialist workshop to arrange this.

You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.

Driving systems
Cruise control
General notes
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select a low gear in good time. For this, you will need to have
selected manual drive program M
( Y page 148). By doing so, you will make use
of the braking effect of the engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic con- ditions make it appropriate to maintain a
steady speed for a prolonged period. You canstore any road speed above 20 mph
(30 km/h).
The speed indicated in the speedometer may differ slightly from the speed stored.
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci- dent nor override the laws of physics. Cruise
control cannot take into account the road,
traffic and weather conditions. Cruise control
is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed, for braking in good time and for staying in
your lane. Do not use cruise control: R
in road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored.

Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
iIf you do not fully release the accelerator
pedal, the
DISTRONICPLUSPassivemes-
sage appears in the multifunction display.
The set distance to a slower-moving vehicle in front will then not be maintained. You will
be driving at the speed you determine by
the position of the accelerator pedal.
You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is
30 km/h.
Driving with DISTRONIC PLUS
Pulling away and driving
The vehicle can also pull away when it is
facing an unidentified obstacle or is driving on
a different line from another vehicle. The vehi- cle then brakes automatically. Be ready to
brake at all times.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary. X
If you want to pull away with
DISTRONIC PLUS: remove your foot from
the brake pedal.
X Briefly pull the cruise control lever (Y page 164) towards you ?.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If no vehicle is detected in front, your vehi-
cle accelerates to the set speed.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle.
In this way, the distance you have selected is
maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed. The vehicle is only accelerated up to the
speed you have stored.
Selecting the drive program
DISTRONIC Plus supports a sporty driving
style when you have selected the Sor Mdriv-
ing program ( Ypage 147). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have
selected the E(AMG vehicles: C) drive pro-
gram, the vehicle accelerates more gently.
This setting is recommended in stop-and-
start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC PLUS supports you when: R you are driving faster than 70 km/h
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front
R you switch on the appropriate turn signal
R DISTRONIC PLUS does not detect a danger
of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted

Setting the specified minimum distance
You can set the specified minimum distance
for DISTRONIC PLUS by varying the time span
between one and two seconds. With this func- tion, you can set the minimum distance that
DISTRONIC PLUS keeps to the vehicle in
front, dependent on vehicle speed. You can
see this distance in the multifunction display( Y page 168).
iMake sure that you maintain the mini-
mum distance to the vehicle in front as
required by law. Adjust the distance to the vehicle in front if necessary.
X To increase: turn control=in direc-
tion ;.
DISTRONIC PLUS then maintains a greater distance between your vehicle and the
vehicle in front.
X To decrease: turn control=in direc-
tion :.
DISTRONIC PLUS then maintains a shorter
distance between your vehicle and the
vehicle in front.
Deactivating DISTRONIC PLUS
There are several ways to deactivate
DISTRONIC PLUS:
X Briefly press the cruise control lever for-wards :.
or
X Brake, unless the vehicle is stationary
If you deactivate DISTRONIC PLUS, you will
see the

Tips for driving with DISTRONIC PLUS
General notes
The following contains descriptions of certain
road and traffic conditions in which you must be particularly attentive. In such situations,
brake if necessary. DISTRONIC PLUS is then
deactivated.
Cornering, going into and coming out of a
bend
The ability of DISTRONIC PLUS to detect vehi- cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles traveling on a different line
DISTRONIC PLUS may not detect vehicles
traveling on a different line. The distance to
the vehicle in front will be too short.
